SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generate reliable unit tests that validate behavior of functions, methods, and classes in isolation, preventing regressions.

Core Features & Use Cases

Deterministic tests that run quickly with no external dependencies.
Guided coverage: covers happy paths, edge cases, and error handling for targeted modules.
Use Case: when implementing a new API or refactoring, automatically produce a test suite to document expected behavior.

Quick Start

Generate a test file that exercises the specified source modules using the project's test framework.

FAQPage Schema

How do I auto-generate unit tests for an existing codebase?▼

Deterministic unit tests run quickly with no external dependencies, validating isolated function behavior. They cover happy paths, edge cases, and error handling to prevent regressions when you implement new APIs or refactor existing modules.

How do I generate deterministic tests with no external dependencies?▼

Generate deterministic tests by targeting functions, methods, and classes to validate behavior in isolation. This produces fast test files covering happy paths, edge cases, and error handling using your project's test framework without relying on external dependencies.

What is the best way to cover edge cases and error handling in unit tests?▼

Cover edge cases and error handling by generating test files that exercise targeted modules in isolation. This guided coverage validates behavior across happy paths and edge cases, producing a deterministic test suite that documents expected module behavior.

Can I use auto-generated unit tests when refactoring a module?▼

Yes, you can use auto-generated unit tests when refactoring. The generated tests validate isolated function behavior, covering happy paths, edge cases, and error handling to prevent regressions and document expected behavior during module changes.

Does auto-generated unit testing work with my project's existing test framework?▼

Auto-generated unit testing works with your project's existing test framework. It produces test files that exercise specified source modules using that framework, validating isolated behavior and covering happy paths, edge cases, and error handling.

When should I avoid generating unit tests for code?▼

Avoid generating unit tests for code with external dependencies or non-deterministic behavior. This approach targets fast, deterministic validation of isolated functions, methods, and classes, making it unsuitable for modules requiring external system integration.
